CVE-2026-4431: Easy Post Submission postId updates permit unauthenticated post tampering

Easy Post Submission through 2.3.0 exposes rbsm_submit_post through wp_ajax_nopriv_rbsm_submit_post. When an unauthenticated caller supplies postId, create_post() does not verify that the caller may edit the selected post. The attacker can overwrite arbitrary posts' titles, content, excerpts, categories and tags, or change the status to draft and effectively unpublish them. The CNA does not disclose the remaining field names or the lower-level post-update function.
